Flexible "Rogowski" coils | current measurement solutions
-
Flexible “Rogowski” coils are modern, safe and flexible current measurement solutions designed for accurate monitoring of high currents without direct interruption of the electrical circuit. The coils are widely used in energy, industry, automation and building engineering systems where reliable current measurement is required in limited or complex installation locations.
Unlike classic current transformers, “Rogowski” coils are without a ferromagnetic core, therefore they do not saturate, offer a wide measurement range, high accuracy and easy installation even around thick, irregular-shaped conductors or busbars.
Main functions
Measurement of high currents (hundreds or even thousands of amperes)
Non-contact measurement – no need to dismantle the electrical circuit
Wide frequency range – suitable for power quality analysis
High accuracy and stability even under impulsive loads
Compatibility with energy analyzers, meters, protections
Flexible design – easy installation in tight spacesApplications
For household users: Monitoring current in residential solar power plants, EV charging stations or main incoming supplies. When safe measurement without power disconnection is required. A solution for energy consumption analysis in smart homes.
For electricians: Fast and convenient installation in panels, distribution boxes, on busbars> A choice for renovations when voltage cannot be switched off. Reduced risk of installation errors and mechanical damage.
For engineers / designers: Used in energy monitoring, power analysis, BMS and EMS systems. Suitable for high currents where classic current transformers become impractical. A solution for Solar, UPS, industrial motors, MCC, generator systems.
For industry and energy sector: Analysis of electrical network loads. Energy control of production lines and equipment. Temporary or permanent measurement solutions during audits and diagnostics.Advantages
Flexible design – suitable for complex installation locations
No core saturation – accurate measurement even at very high currents
Fast installation without power disconnection
Wide current and frequency range
Lower weight and size compared to traditional current transformersDisadvantages
Requires an integrator or a compatible measuring device
Slightly more complex signal processing compared to classic CTsFlexible “Rogowski” coils are a professional and future-ready solution for those who value accurate, safe and versatile current measurement. Suitable both for household energy monitoring solutions and for complex industrial and energy systems.
